IMPROVEMENT IN INKING-APPARAT US EOE PRINTING-PRESSES.

TO ALL WHOM IT MAY OONOERN:

Be it known that I, THOMAS L. BAYLIES, of the city of Riehniond, and State of Indiana, have invented a new and usel'u'l Improvement in Chroma-tic InkingeApparatus; and I do hereby declare that the following is-a full, clear, and exact description ofthe same, reference being had to the accompanying drawings7 making a part of' this specification, iu whichvliigure 1 is a perspective view,

Figure 2 a plan view, and

Figure l a longitudinal section.V

The saine letters .in the difierent figures relate to corresponding parts of 'the invention.

My invention rel-stes to an inliing-apparatns to be used in connection with printing-presses, by means ct which printing may be donc in different colors at one and the same impression.

To enable others skilled in the art to multe and use my invention, I will proceed to describe its construction and operation. i

A represents the structure or frame of the press Lo which the hiking-apparatus is applied.

B is the type-bed supported and 'movable in the grooves H and H.

C represents the form, on which are located the diiferent colors representing the diil'erent lines ot' type.

D and D are rollers for inking the type.

e, e, and e, each represents a set of hiking-slats, which sets are attached respectively to frames couv posed of one of the transverse bars a, a, and c", and two ot' the longitudinal bars Z1, b', and b, (one at each end.) One end of the longitudinal bars is secured in any'suitable manner to the corresponding transverse bar.4 The opposite ends of said longitudinal bars and one end of all the inliing-slats yare hinged bybeing looped or hooked on the transverse rod g. The latter is supported by its ends resting in ears zt and u attached to bed B, as shown in tig. 2. f

The transverse bars a, a', and a, of the frames are cach provided with wrists at their ends, which wrists rest in grooves t t t in each side of the frame A.

E, E', and E, are inking-rollers, each oi' whiclris supplied (in any of the ordinary forms) with ink of a different color.

The frames to which the hiking-slats, e, e, and c, are attached are made of successione-1 sizes, by which, when brought together, they may occupy positions one within the other, and thus the upper surfaces oi' all the inking-slats conform, to the same horizontal plane by correcting the difference caused by the different positions 0f the grooves t, t', and t, in which the ends of the transverse bars a, a', and tt rest, which is done by notching the ends of slats In, b, and l to dil`erent depths where the latter are connected with the transverse bars.

The slat of the different sets are arranged in intermediate positions, according to the-order desired for4 the diierent colors. The width of said slats is made suitable to give the desired breadth of color.

1 The upper and lower grooves tand t diverge at a point nea-r the inkingvrollers E, E', and E, by which the frames carrying the upper and lower sets of inlring-slats are separated.

The operation of the apparatus is as fellows:

The movement of the bed B, which carries the type baci: and forth for the purposes of inking said type and taking impressions therefrom, also causes a reciprocating movement of the inking-slats, and frames to which they are attached, the wrists at the ends ci the bars a, a', and a, sliding respectively in the grooves t, t', and t, thus bringing said slats together, and in uniform contact with the under surfaces of rollers D and D.

Each set of inking-slats reeeives'its respective-color from the corresponding one of the rollers E, E, and E", the upper and lower sets? of slats being brought in contact with their respective roller by means of the diverging directions of the upper and lower grooves, which being followed respectively by the wrists of said Slat-frames, carry the upper slats e in contact with roller E, and the lower slats e in contact with roller E", as seen in fig. l. The intermediate groove t being in a direct line, carries the slats e in Contact with roller E. Thus the sets of slats receive their particular color, which they, in turn, transfer in belts to the rollers D and D. As the slats, by their forward movement, are brought n'c-ontactuvith said rollers the latter again transfer the colors, to the type, from which the impressions are taken and the operation completed.

The rollers E, E', and E, have their bearings in vertical slots, 1,1', and I, in the sides of the frame, as seen in fig. 3, thus allowing said rollers to adapt themselves vertically to the changing positions of the slats. The necessary mechanism maylso be applied to give the rollers E, E', and E, a lateral or en l motion for the better distribution of ink on their surfaces, if found necessary;

The construction of the inkingappaatus,las hereinI set forth, is particularly applicable to a cylinder-press of the table-distribution. class. Some'modtications would be necessary to make it applicable to presses of other descriptions.

Having thus fully described my said invention, what I claim, and desire to secure by Lettersv Patent, is

1. The nking-slats e, e', and e, hinged and so arranged in sets as to all occupy .the same horizontal plane, and also to admit of `their beinfar separated and brought in contact with dilerent-eoloi'ed inking-rollers, substantially as described and for the purpose set foi-th. i

2. The grooves t,t, andi, in the sidesel' the frames, in combination with the inking-slat framesor their equivalents, by which said inking-slats are' directed against the surfaces of their respective hiking-rollers, substantially as described and for the purpose set forth.
